vacuum-CLEANER ATTACHMENT'FOR MOTOR VEHICLES.

Application. filed June 14, 1926. Seria1.No. 115,920.

This invention relates to certain new and useful improvements in vacuum cleaner attachment for motor vehicles and has for one of its objects to utilize the exhaust or suction created in the exhaust pipe of the motor vehicle engine to produce a suction for a vacuum cleaner member.

A further object of the invention is to provide a vacuum cleaner attachment for motor vehicle engines wherein the cleaner attachmentis associated, with the exhaust pipe and embodying a manually operable valve structure for causing the exhaust gases to flow either directly through the exhaust pipe or be diverted through a Venturi tube with which a vacuum cleaning pipe and nozzle are associated. f

A still further object of the invention is to provide a vacuum cleaner attachment of the type above set forth wherein a single valve is movable into engagement with a pair of valve seats arranged at right angles to each other for controlling the direction or how of exhaust gases either directly through the exhaust pipe or through a Venturi tube with which the vacuum cleaner attachment is associated with means cooperating with the valve and acting in opposition to the force of the exhaust gases to en sure heating movement of the valve upon one of its seats.

A. still further object of the invention is to provide an improved type of cleaner noz= zle wherein the nozzle head or mouth is provided with partitions forming a rela tively wide intermediate mouth opening and relatively narrow end mouth openings with a brush element removably attached to the nozzle head.

With the above and other general objects in, View that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts herein-,, after more fully described, shown in the ac companying drawings and claimed.

In the accompanying drawings wherein like reference characters are employed to designate corresponding parts throughout the severa views,

Figure 6 is a detail sectional view taken on line 66 of Figure 4. p

As shown more clearly' in Figs. 1 and 4 to (i, the vacuum cleaner attachment and suction creating device is associated-with the exhaust pipe 1 of'the motor vehicle engine and may be interposed in the exhaust pipe at the desired point with respect to the muifler and said suction creating device comprises a "l '-fitting'having'a cross head 2 and a dependlng leg 3; The cross head 2 embodies an inlet end 4 and an outlet end 5 into which sections of'the exhaust pipe 1 are inserted and retained by the stud screws 6 and clamping screws 7 associated with split portions and ears 8 at the lower sides of the cross head 2 as shdwn in Figure 4.

The upper end'fof'the'cross head 2 is provided with an-open in'g 9 aligned with the passage through the "depending leg 3 of the T-fitting, the opening 9 being closed by the cover plate 10 fastened-Finjposition'by the screws 11 and said coverplate carries an outwardly directed ear 12 extending laterally of the T-fitt-ing as shown in Fig. 1 for purposes presently to appear. The T-fitting defines the central area 13 in which a valve is movable and the valve controls the flow of exhaust gases entering the inlet end 4 and area 13 by causing the same to pass into the outlet end 5 of the cross head or through the depending leg 3. A circular valve seat 14: is disposed between the area 13 and the outlet end 5 of the cross head while a circular valve seat 15 formed by the provision of an annular shoulder is located at the lower end of the depending leg 3. The shoulder forming the annularvalve seat 15 is pro vided with diametrically opposite grooves 16 that receive opposite ends of the blade or rib 17 for purposes presently to appear.

As shown in Figs. 1 and 4: a web 18 extends between the depending leg 3 and outlet end 5 of the T-fitting cross head and having a socket 19 therein provides side walls for the journal bearing of the shaft 20 upon elbow flange 30 being an end opening which the curved link 21 is fixed within the socket. The other end of the curved link pivotally supports as at 22 the disk valve 23. The shaft 20 projecting through the side walls of the web 18 has an elongated angularly extending handle 24 upon one end thereof for the manual operation of the disk valve 23. As shown in Fig. 4, the valve 23 is movable into engagement with either of the seats let or 15 and as shown by dotted lines in Fig. 3, the exhaust gases entering the T-fitting are diverged through the dending leg 3 and into a Venturi tube now to be described. The valve is illustratedby dotted lines ina position assumed during movement thereof toward the valve seat 13. The coiled spring 25 is attached to the ear 12 of the cover plate 10 and also to the pin 26 carried by the lever 24 and said spring being disposed to exert closing movement for the valve 23 at opposite sides of the bearing shaft 20 carrying the valve and curved link.

A Venturi tube and suction pipe carried thereby is associated with the lower end of the depending leg 3 and comprises a tube section 27 having a reduced Venturi portion 28 with an elbow 29 at the opposite end of the tube. The open end of the elbow 29 is provided with aflange 3O mating with the flange 1 upon the lower end of the depending leg 3 and said flanges are secured to gether by the screw boltsv 32 and 33, passing through openings in the flange 30 and entering the flange 31. To accommodate mounting of the stud screw 33 in view of the relative positions of the adjacent edge of the elbow flange 30 and elbow body, said Venturi tube and elbow are provided with spaced reinforcing ribs 34 to provide a sliding clearance for the head of the stud screw 33 as shown in Fig. 4, the opening 35 in the slot which permits positioning of the stud screw 33 in the leg flange 31 and the subsequent sliding of the flange 30 into position, after which the stud screw 32 is passed through the opening in the flange 30 to be threaded into the flange 31. This construction and operation for connecting the T-fitting to the Venturi tube is clearly illustrated in Figs. 4 and 6. A. bearing ring 36 is formed at the closed end of the elbow 29 in line with the tube 27 and in which the suction pipe 37 is mounted, one end of the suction pipe projecting slightly outwardly of the bearing 36 for thereception of the flexible tube-3b while the other end of the suction pipe terminates within the Venturi portion 28 of the tube. It will therefore be seen from an inspection of Figure 4 that exhaust gas flowing through the exhaust pipe 1 will be diverted by the valve 23 engaging the valve scat l l at the outlet end 5 of the T-fitting to cause the exhaust gas to flow through the depending leg 3 and tube 27 to create a suction in the pipe 37 to which the flexible hose 38 is connected that carries a vacuum nozzle 39 at its other end. hen the valve 23 is. operated'by the lever 24L to be shifted to a position to engage the valve seat 15, action of the suction device is terminated and the exhaust gas flows directly through the T fitting and outlet end' of the exhaust pipe 1. When the valve 23 is moved toward the valve seat 15 from its position as shown by full lines in Fig. 4, the exhaust gases entering the T-fitting and contacting the valve disk 23 will have a tendency to cause the valve 23 to assume a perpendicular position-relative to the valve seat 15 and to ensure seating movement of the valve 23, the lower edge thereof is engaged by the upper edge of the rib 17 to cause a tilting action of the valve against the action of the exhaust gases to move the valve to a horizontal position as indicated during the act of closing movement as shown by dotted lines in Figure 4.

The nozzle 39 shown in Fig. 2 embodies a widened and flattened mouth 40 having an inclined partition 41 adjacent each end of the mouth to provide a relatively wide intermediate entrance opening 42 and restricted end opening 4.3. A nozzle mouth of this character permits a more thorough cleaning of the interior of a motor vehicle, especially at the edges of floor mats or rugs as the entire suction of the entrance opening of the nozzle mouth may be closed except one of the end passages 41 which may be disposed over the edge of a mat to exhaust dirt or other foreign matter from the floor or other places. The brush element 44 shown in Figure 3 comprises a twisted core 45 that may be placed in enclosing relations with respect to the widened and. flattened mouth 0 for loosening the dust and dirt and provide for a more thorough cleaning operation. Vhile there is herein described the preferred embodiment of the present invention, it is, nevertheless, to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
